Mild Gulf Stream current factors into Weather Networkâs seasonal outlook
On the heels of a cold and snowy winter and a fairly cool spring, Newfoundland and Labrador can expect a typical summer, according to the Weather Networkâs seasonal outlook for the province.

Weather Network meteorologist Dayna Vettese said the Atlantic Oceanâs Gulf Stream current will continue to be mild, resulting in more-temperate temperatures for Newfoundland and Labrador.
âThat means temperatures on average between about 17 to about 21-22 C,â said Vettese, who is based in Toronto. âThatâs about average for the summer.â
Total rainfall amounts of between 250-300 millimetres are anticipated for Newfoundland and Labrador based on the Weather Networkâs summer outlook.
Also of note for the province is a developing El NiĂ±o of warm ocean temperatures on the Pacific coast of South America.
âWhat that normally means for the Atlantic Ocean is suppressed tropical storm cyclone activity,â said Vettese.
âThat doesnât mean we wonât get the formation of tropical storms or hurricanes, but there should be less of them out there. So thatâs something for us to watch for as we head into August, September and October.â
Daily high temperatures recorded at St. Johnâs International Airport this spring have most often been below average. Vettese said residents can expect temperatures to be a bit up and down in the near future.
âThe next week ahead, we look a little bit on the cool side, but then towards mid-June we should start to come up a bit in temperatures and level off to more of a near-normal situation for Newfoundland.â
The near-normal prognosis for the summer is not shared throughout the country.
âDue to the developing El NiĂ±o, we actually think that areas along the Western portion of Canada â mainly British Columbia up through the Yukon â will have a warm and dry summer,â said Vettese.
âWhereas opposite of that, right across Saskatchewan, Manitoba and into Ontario, we expect a swath of unsettled and cooler weather â almost a continuation of that trend we saw through the spring.â
